Hands of Hextor

By use of this spell the caster causes the immediate growth of two new pairs of arms, allowing him or her the opportunity to launch a great many attacks on an opponent. The arms will grow instantaneously, and the caster’s clothing will reshape itself to allow the arms the same adornement (non-magical in nature, of course) that the priest’s real arms have. These four new arms can be used as the priest wills, and may wield weapons without penalty, subject to normal proficiency requirements. They may also be used to carry bucklers, which is often a strategy used by priests casting this spell.
Each arm has 15 hit points that are separate from the caster’s, and can be destroyed by a dispel magic spell for each arm. The arms are otherwise 100% magic resistant.
